The <em>miR-577</em> expression did not differ between groups (<em>p</em>-value, 0.2). A weak negative correlation between the two miRNAs was observed, suggesting a potential inverse correlation. Receiver Operating Characteristic (ROC) curve analysis indicated that <em>miR-30a-5p</em> may serve as a biomarker for epilepsy.</div></div><div><h3>Conclusion</h3><div>This study suggests that <em>miR-30a-5p</em>, showing upregulation and according to the ROC curve may act as an early epilepsy detection biomarker. Conversely, miR-577, despite a decrease in expression, is deemed unsuitable as a biomarker due to its lack of statistical significance and poor diagnostic performance.</div></div>","PeriodicalId":12673,"journal":{"name":"Gene Reports","volume":"39 ","pages":"Article 102214"},"PeriodicalIF":1.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
